Attention
Different browsers interpret web page
languages (HTML/
PHP/Javascript/CSS) differently at default.
I tuned up this site best for Google Chrome, a most popular
browser running on desktops/tablets/
notebooks/mobile phones.
Other browsers (Firefox/Edge/IE/
Opera///) might exhibit weird appearance that I do not aim at.
